To all whom it may concern:

Be it known that I, JACOB SCHOONHOVEN, a citizen of the United States,residing at Shannon, in the county of Carroll, State of Illinois, haveinvented certain new and useful Improvements in Shocker-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same.

'This invention relates to farm machinery and more particularly tomachines for they come from the binder, and for placing the shocks soformed in upright position upon the ground.

Another object is to provide a machine so arranged that its motion overthe ground will be neutralize 1 at the time that a shock is beingdeposite I on the ground so as to prevent the shock from being pulledover before it is released from the mechanism.

Another object is to provide a machine so constructed that it will bepractically automatic in its operation.

Another ObJGClZ 1s to'provide a machine including means for interruptingthe dlscharge v of bundles from the binder during the time that oneshock is being deposited upon the ground.

"Other objects and advantages will be apparent from the followingdescription:

Fig. 11 is a fragmentary top plan, showingthe shock former indischarging posiion.

Referring now to the drawings the pres ent invention comprises ahorizontally dis- .posed frame 15 including parallel side members 16 and17 and a connecting front end member 18.

The side member 17 is provided with hooks 19 extending outwardlytherefrom and adapted to be engaged with the frame work of a binder A tohold the present mechanism to the binder. -Additiona1 fastening devicesmay be used if desired. The

rearward end of the side member 17 carries a caster wheel 20 which actsas a support for the rearward'end of the machine. A transverse shaft 21is mounted upon the under faces of the side members adjacent to theforward end thereof and extends outwardly beyond the member 16, thisshaft carrying a bull wheel 22 upon its outer end, the wheel beingprovided with asprocket 22' mounted for rotation therewith.

Two guide rails 23 and 9A are provided, these rails being secured attheir forward ends to the connecting member 18 of the frame, with therail 23 adjacent to the member 16 ofthe frame and with the rail 24adjacent to the member 17 of the frame. The two rails extend rearwardlyapproximately in parallel relation for a short distance, as indicated at25 and beyond this portion 25 the rail 23 is curved upwardly andrearwardly and then curved laterally and rearwardly as indicated at 26to extend approximately across the frame, when it is curvedlongitudinally and rearwardly as indicated at 27 to a point adjacent tothe rearward end of the frame where it is directed downwardly andrearwardly as indicated at the inner face of the member 17 in a bracket30 which holds the rearward portion of the rail spaced from the memberl7.

The rail 24, rearwardly of its portion 25 is curved downwardly andrearwardly and then laterally as indicated at 31, and is then curvedupwardly and rearwardly as indicated at 32 to a point horizontallyopposite the portion 27 of the rail 23, when it is turned downwardly andrearwardly as indicated at 33 in parallel relation to the portion 27 ofthe rail 23 and at the opposite side of the frame therefrom. Therearward portion of the rail 23 is turned more directly downwardly asindicated at 34 in parallel relation to the portion 28 of the rail 23,the rearward extremity of the rail 24 being mounted upon a bracket 35projec'ting from the inner face of the member 16 to hold the rearwardportion of the rail 24 in spaced relation to the inner face of themember. It will thus be seen that each rail has its ends mounted atopposite sides of the frame,-the rails having a general longitudinaltrend, and that the rails are crossed at points between their ends, thecrossing portions having compound curves therein so that one rail iscurved downwardly while the other rail is curved upwardly, the rearwardportions of the two rails being inclined downwardly in parallel relationand having more abrupt downward bends at points adjacent to theirrearward extremities. In this way there is formed what may be termed ahelical track extend ing longitudinally of the frame.

A bar 36 is mounted to extend between the rails 23 and 24, this barhaving reduced extremities 37 forming pin'tles to receive plates 38which are provided with outwardly extending parallel stub shafts 39 attheir ends, these stub shafts having mounted thereon peripherallygrooved rollers 40. These rollers are thus mounted in pairs at each endof the bar 36 and each pair of rollers receives one of the rails 23 and24 therebetween. By this structure the bar may be moved from end to endof the track which is formed by these rails, the rollers acting tosupport the bar upon the rails, and the pivotal connection of the barwith the plates 38 permitting rotation of the bar upon its longitudinalaxis.

The bar 36 serves to support a shock former 41 which is mountedthereupon be- 4 tween the ends thereof. This shock former consists of acentral, longitudinal member 42 which is secured at one end u on the barby means of bolts 43 and 44 passed therethrough and through the bar,blocks 45 being engaged with these bolts between the member 42 and thebar to form a guide passage 46 between the member 42 and the bar for apurpose to be presently described.

The 'shock former also consists of two transversely curved side members47 extending longitudinally of the member 42 and hinged to thesidesthereof with their concave surfaces directed inwardly, these sidemembers 47 being tapered toward one end and being disposed with theirmajor ends adjacent to the bar 36. The member 42' guiding the end'of theshock iformer which projects from the bar. This means includes a rod 48secured to the outer end of the member 42 and extending longitudinallytherebeyond. An upright stanchion 49 is secured to the member 16 of theframe adjacent to its rearwardendand has a transverse opening 50 in itsupper end. Alateral bracket 51 is carried by the upper portion of theisjanglgio gxtepds inwardly of the" framdldzib ithelspace between therearwa d portions of the rails 23 and 24,

"thisbracketchjaving an eye 52 at its inner end which registers with theopening 50' to receive a horizontal rod 53 having threads 54 formedthereon to extend at opposite sides of the upper end of the stanchion.Nuts 55 are engaged with the rod at opposite sides of the stanchion andby means of these nuts the rod may be adjusted laterally to shift itsinner end transversely of the frame 15.

Upon the inner end of the rod 53 there is pivotally mounted a transverseplate 56 and this plate carries a pair of peripherally grooved rollers57 which receive the rod 48 therebetween. These rollers thus form amounting for the rod 48 which permits of longitudirm spect thereto, andwhich also permits of rotary movement of the rod upon its longitudinalaxis. The pivotal connection of the plate 56 with the rod 53 providesfor swinging movement of the rod 48. The adjustment of the rod 53permits of proper positioning of the rollers 57 to prevent any bindin ofthe rod 48 therebetween.

eans is provided for moving the side portions 47 of the shock formertoward and away from each other. This means includes a shift rod 58mounted lon 'tudinally upon the outer face of the mom or 42 and slidablyengaged in the passage46 between the member 42 and the bar 36, andextending beyond the end of the member 42 which is l movement of the rodwith re-' connected with the bar 36. This shift rod has its opposite endmounted in a guide 59 i which is also secured to the member 42. Pivotedto the shift rod 58 there are a pair of diagonally extending resilientarms 60 which diverge toward the bar 36, and these arms are pivoted tothe side portions l7, and thus, when the shift rod is moved in thedirection of the minor ends of the side members 47 the side members willbe moved away from each other. When the shift rod is moved in theopposite direction the side members will be moved toward each other andto hold the shift rod with the side members separated to the fullestextent, a

spring 59 is engaged with the pivotal conlies adjacent to the member 17of the frame.-

A cable 64 is looped around the drum and has its ends led oppositelytherefrom. One

end of the cable passes from the drum at the upper side thereof and overthe member 18 of the frame and this end of the cable is connected bymeans of'a helical spring v with that end of the bar 36 which liesadjacent to tie member 17 of the frame when the bar is at the forwardlimit of its movement. The opposite end of the cable is carried beneaththe frame diagonally to the rearward end of the member 16 of the framewhere it is passed upwardly around a vertical pulley 66 carried by therearward end of the member 16 at its inner face, beyond which pulley thecable is carried forwardly and diagonally to be attached to the bar 36at a common point with the attachment thereto of the spring 65. It willthus be seen that, with the drum rotated clockwise,

or with its upper portion toward the rearward end of the machine, thelower portion of the cable will be wound upon the drum and the shockformer will be moved rearwardly, the upper portion of the cableunwinding from the drum to permit such movement. Na, as -the bar 36which carries the shock rormer moves along the rails 23 and 24, tlformation of these rails will shift the but end for end with respect tothe machine, which will result in turning the shock former upside down,as the bar traverses the crossed portions of the rails, the rod 48working between the rollers 57 as will be understood. The bar will thentravel along the rearward parallel portions of the rails 23 and 24, andat the same time the minor end of the shock former will be elevated bythe cooperation of the rollers 57 and the rod 48, the parts being soarranged that the shock former will have been brought approximately to avertical position at the time that the bar 36 reaches the rearmostportions 28 and 34 of the rails. Movement of the bar along theseportions of the rails gives the shock former greater downward movementwith some rearward movement as will be understood. Now, if the movementof the cable be reversed, the shock former will be returned to itsoriginal position to lie open side up and with its major end directedforwardly. As will beunderstood, when the shock former is in verticalposition at the rearward limit of its movement, it lies with the freeedges of its side portions directed rearwardly and with its major enddirected downwardly.

To rotate the drum 63, with its shaft 62 in either direction, a lateralstub shaft 67 is mounted in the member 17 of the frame and upon theinner end of this shaft there is rotatably mounted a gear wheel 68 whichmeshes with a gear wheel 69 carried by the shaft 62, and the gear wheel68 is provided with a clutch surface 70 upon it outer face.

Mounted upon the outer end of the shaft 67 there is a sprocket 71rotatable upon the shaft and this sprocket is connected by means of anendless chain 72 with a sprocket 73 carried by the shaft 62. Thesprocket 71 has an inner clutch surface 74, and the clutch surfaces 74:and 70 are considerably spaced from each other to receive thercbetween asprocket 75 having oppositely directed clutch surfaces 76 and 77 forcoaction with the clutch surfaces 74 and 70 respectively. The sprocket75 is revoluble upon the shaft 67 and is also slidable upon this shaftso that it may be moved to engage either pair of clutch surfaces.- Achain 78 is engaged with the sprocket 75 and also with the sprocket 22of the bull Wheel. It will, thus be seen that when the clutch surfaces74 and 76 are in engagement with each other the sprockets 71 and 73 willre volve the shaft 62 to wind the upper portion of the cable upon thedrum and move the shock former forwardly. When the clutch surfaces 70and 77 are mutually engaged the gears 68 and 69 will revolve the shaft62 and the drum in the opposite direction to move the shock formerrearwardly. The ratio of the gears 68 and 69 is such as to rotate theshaft 62 at such a speed that the shock former will be moved rearwardlyat approximately the same rate that the entire machine is movedforwardly over the ground as the shock former traverses the rearmostportions of the rails 23 and; 24 along which it passes. By thisarrangement, the forward movement of the machine is approximatelyneutralized so that theshock former is practically free from horizontalmovement with respect to the ground during that portion of its movementjust referred to, and during the time that it is exercising itsischarging function as .Will be later brought out. The ratio of thesprockets 71 and 73 is such' as to return the shock former to theforward end of the machine as quickly as possible consistent with properoperation.

To shift the sprocket 75 upon the shaft 67, a lever 79 is mounted in abracket 80 secured to the frame, and is shiftable in the bracketlaterally of the frame. This lever carries a yoke 80 which is en agedwith the sprocket 75 for movement 0% the sprocket slidably upon theshaft 67. Inward movement of the lever 7 9 thus results in engagement ofthe clutch surfaces 70 and 77 while outward movement of the leverresults in engagement of the clutch surfaces 7e and 76.

A cable 81 for tripping the clutch to dis connect the sprocket 7 5 fromthe sprocket 71 is provided and this cable is also utilized to bring thesprocket 75 into position to drive the gear 68. to the lever 79, iscarried through the frame transversely and is secured to a suitable footlever 82 mounted within reach from the drivers seat of the binder A.

A rod 83 is mounted upon the member 16 of the frame to extendlongitudinally thereofand to lie therebelow. This rod 83 has its forwardend turned downwardly and connected by means of a link 84 with the lever79. The rearward end of the rod 83 is turned inwardly as shown in 85 andit will be seen that downward movement of the end 85 of the rod 83 willthus result in outward movement of the lever 79, which will engage theclutch surfaces 74 and 7 6 for operation of the parts to move the shockformer forwardly.

Means is provided for closing the shock former just prior to thebeginnin of its rearward movement. This means includes a spring latchsecured to the member 18 of the frame and extending rearwardly andadapted to engage with a lug 87 carried by the end of the shift rod 58which lies beyond the major end of the shock former. As shown in thedrawings the spring latch is indicated at 88. The shift rod is alsoprovided with additional lugs 89, and pivotallv connected with the bar/36 there is a latch 90 which is held in position for engagcment of theselugs 89 by means of a spring'91. The latch carries a trip finger 92which extends at right angles from the shock former to projectdownwardly when the shock former is at the forward end of the machine inhorizontal position and to project forwardly when the shock former Thecable 81 is connected is at the rearward end of the machine in 66vertical position.

Now, with the shock former at the forward end of the machine and open,it lies below the discharge table B of the binder A. to receive bundlesof grain therewithin. When filled, the foot lever 82 is operated to movethe sprocket 75 from neutral position into position to drive the gear68. This will result in rotation of the drum 63 to move the shock formerrearwardly but at this time the latch 88 lies in engagement with the lug87.. so that the shift rod is held stationary while the shock formermoves with respect thereto. The side portions of the shock former will"thus be brought together, and the spring 91 will move the latch 90 intoen- 'gagement with one of the lugs 89 to hold the shift rod with theshock former closed.

When the stop finger 61 has been brought into engagement with the guide59, move ment of the shock former with respect to the shift rod will bearrested, if it has not already been stopped by the presence of grainwithin the shock former, and continued movement of the drum, tending tomove the shock former rearwardly will cause the lug 87 to disengage fromthe latch 88, this being permitted by the resilicntnature of the latch,but the shock former will be held closed by the latch 90.

Now, when the shock former has reached the rearward end of the machineand is moving downwardly and rearwardly along the rearward portion ofthe rails, the finger 92 will be brought into contact with the inwardlyturned end 85 of the rod 83 which lies in position to be so engaged bythe finger 92. This will result, first, in tripping of the latch 90 torelease the shift rod 58,- when the shock former will be thrown open bythe spring 59, as will be understood. The parts are so arranged thatthis will occur before the shock former reaches the rearward limit ofits movement and since its rearward movement is also downward movemcntat this time the finger 92, pressing upon the end 85 of the rod 83 willmove this end downwardly to throw the sprocket 75 into position to startthe return movement of the shock former to the forward end of themachine.

The finger 92 has an additional function. It will be noted that thecable 81 extends across the frame in position to be struck by the finger92 as the shock former is moved forwardly. This occurs before the shockformer has reached the forward limit of its movement and the arrangementis such that there is sufficient continued movement of the shock formerto move the cable through its engagement by the'finger 92 sufiicientlyto bring the sprocket 75 and its clutch si'rfaces into neutral positionwhen, of course,

the movement of the shock former will be arrested. At the same time, thelug 87 has contacts with the finger at a point close to the center ofpivotal. movement of the latch and thus there is not suflicient leverageto move the latch against the action of the spring 91 and thus interferewith the operation of the latch. However, this same function can beaccomplished by a separate depending member carried by the shock formerif desired.

The mounting of the latch 90 is shown in detail in the drawing. Aspreviously stated, bolts 44 and 43 are passed through the bar 36 to holdthe member 42 of the shock former thereto, the blocks 15 being disposedbetween the member 42 and the'bar. At the opposite side of the bar 36from the shock former, a bracket 93 is engaged with the bolt 14 andextends beyond the bar 36 toward the end of the shift rod 58 whichcarries the lug 87. This bracket has the latch 90 pivotally connectedtherewith and lying with its lip 90 directed toward the outer end of theshift rod and lying in position to engage the lugs 89. The finger 92 iscarried by the latch and extends away from the shift rod as alreadydescribed.

A bracket 94 is engaged with the bolt 43 at the opposite side of the bar36 from the shock former and extends at right angles from thelbar 86 inapproximately parallel relation to the finger 92. This bracket has oneend 94: turned to extend over the finger 92 in spaced relation theretoand this end of the bracket has a rod 95 slidably engaged therein, therod being fixed ,to the finger 92 between the ends of the finger. Thespring 91 is engaged with the rod 95 between the bracket 9%. and thefinger 92 and is arranged to hold the finger yieldably against movementtoward the bracket 9-l so that the finger is held with the latch 90 inposition to,

rupting means comprises two brackets 96 and 97 mounted upon the sidemember 17.

of the frame in spaced relation longitudibelly of the member and at avpoint opposite the shock former transversely of the machine when theformeris in receiving position. These brackets 96 and 97 thuslie-beneath the discharge table B as illustrated.

A horizontal shaft 98 is journaled in the upper ends of the brackets 96and 97 and has a pair of downwardly extending lateral arms 99, oneadjacent to each end. A pair of a-rcuate fingers 100 are carried onev byeach of the arms 99 and extend inwardly of .the machine with theirextremities directed.

upwardly and t arrangen'ient of these parts is such that when the shaft98 is rocked in one direction, the fingers 100 will be moved to projectupwardly over the end of the discharge table to prevent the passage ofbundles therefrom. From the drawings it will be seen that this occurswhen the shaft 98 is ro cked to move the arms 99 inwardly of themachine. When the shaft is rocked in the opposite direction the fingerswill be shifted to bring their upper extremitiegs below the uppersurface of the discharge ta le.

The shaft 98 carries at its forward end a depending finger 101 whichcarries a laterally extending pin 110, the latter being en-. gaged in aslot 111 formed in the upper end of a rod 112, pivoted at its lower end,as shown. This rod 112 carries an outwardly extending rod 102 engagedthrough a guide opening 103 in the bracket 96 and provided with a stop10 1 at its outer end. A spring 105 is engaged with the rod 102 betweenthe finger 101 and the bracket 96, the spring-being arranged to hold thefinger yicldably and with fingers 1'00 extending above the dischargetable in operative position.

The side portion 417 of the shock former which lies in the direction ofthe member 17 of the frame when the .shock former is in receivingposition, carries an outward extending block 106 which is provided withan outer beveled edge107, the major end of this block being directedrearwardly so that the 7 against movement outwardly of the machinebeveled edge 107 slants inwardly and forwardly. This block is sodisposed that, as the shock former is moved toward the front end of themachine, the bevelededge 107 will engage the finger 101, when furtherforward movement of the shock former will cause the finger 101 to moveagainst the ac tion of the spring 105, thus bringing the fingers 100into inoperative position. When the shock former reaches its forwardlimit of movement the block 106 lies with its rearward portions of itsbeveled edge against the finger 101 so that the fingers 100 are held ininoperative position during the filling of the shock former.

N ow, as describedin the foregoing when 1 the shock former is filled,the action of the mechanism is to move the side portions 17 of theshockformer toward each other.

106 will of course be moved inwardly, when the finger 101 will be freeto move under the action of the spring 105 and the fingers 100 will beprojected above the discharge table to prevent the passage of additionalbundles therefrom. By reason of the fact that the fingers 100 arecurved, their points are projected not only above but over the dischargetable toward the next bundle discharged and thus the fingers 100 lie inposition for engagement of their extremities lnto the bundle, thussecurely holding the latter.
